TO ALL WHOM IT MAY CONGERN: r

Be it known that I, JOSEPH DICK, Jr., of Canton, in the county of Sterk,'and State of Ohio, have invented certain new anduseful Improvements in Harvester-Rakes; and I do lierehy'declnre the following to he a. full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of a grain-platform, having my improved rake attached, taken from the outer front corner of the platform, and showing the rake descending upon said platform into position to sweep the grain therefrom. l

I Figure 2 is a grain-side elevation of the same, showing the rake in its elevated positio'n after having swept the platform. I

Figure 3 is an end elevation, with the rake in position represented in iig. l.

Figure 4 is a plan or top view of the rake-gearing; and

Figure 5 represents the rskeilatch, which holds the rake in its elevated position, detached.

Similar letters of reference denote corresponding parts in all the figures.

My invention consists in anovel arrangement of tho rake-gearing', whereby all the movements ofthe rake, both reciprocating and rising and falling, are made positive and regular, whatever may ne the position of the platform in conforming to the surface of the ground over which it is drawn; whereby, also, it is brought into compact shape, end mounted upon a single plate or casting attached to and removable from or with the platform or hoger-har, as hereinafter enpleined,

t further consists in the arrangement of `the gearing relative to the shaft or support upon or about which the relie vihrates; in the arrangement 'of the sector-plate and segment-pinion, qwhich control the rising and falling inovetnents of the rohe; in the construction and manner of combining the vibrating arms carrying the rake, and the devices for raising and depressing the same; in theu arrangement of the latch for holding the rake in its elevated position dni-ing its forward. or return movement; and in the mnnner of operating the lever for releasing Said latch, to permit the descent of the rake upon the platform, as hereinafter explained.

ln .the accompanying drawings, A represents the platforn of the machine, made in quadrant form, and designed to he attached to the iinger-'oar of a harvester, either hinged or rigid, in the usual manner. B is a gear-plate, upon which the vibrating rake C and rake-gear are mounted, made in form substantially as repre sented in figs. 'l and adapted to receive standards e a, to support the horizontal shaft b, and provided with soci-:ets or bearings, c, to receive the vertical crank and raltelshafts or supports hereinafter described. The standards' a are bolted or otherwise irmly 'secured to gcarplate B, and are provided at their upper ends with tubular or eye bearings, in which the shaft B is mounted. Said' shaft is provided at its inner or main-frame end with agirnhal or universal joint, and is designed. to he en extension of a shaft connected and driven from the moin frame oroxle hut adapted to conform to the movement of-thepla'tform, 'D is a bevel driving-wheel, luointed on shaft D, and gearing with the bevel-crank wheel E, made as represented, and arranged horizontally underneath shaft b, and between standards a rr, bent as shown to receive it. The hevel-wheel E is attached to the upper cud of avertical shaft, r2, mounted in alt-uhular socket, c, in plate B, and hasattached to its face au eccentric or 'crank-pin, e, from which, through pit-nianf, motion is imparted to the rake. The opposite or rear end of pitnmnfis connected to a vibrating tubular arm, F, swinging on an upright or vertical shaft, g,- mounted in a socket in gear-plate B, in which tubular'arm or raketten-ier the inner end of' the angular rake C is inserted, in such manner as to be free to turn, to accommodate the necessary rising and falling movements of' the rnlre, retained in position therein hy means'ofa segment lip or flange on the outer end of armv F, and an everhanging hook or lip formed upon or attached Ato the turning-arm C', or to a segment-pinion, F, mounted upon and turningr said rake-arm. The attachment of the pitinan te the arm F is made through an adjustable lug or block of dove-tail or equivalent form, fitting in a corresponding socket in the arm, and made laterally adjustable by 'wedges or keys, teva-ry the distance of the eye freni the centre or shaft, and thereby change the throw of the rake, and the pitman, instead of connecting directly with the relie-carrier, may connect with a heel or branch 'thereof on the frame side of rakepivot,`andthe inner standard c may be varied in form to acooinmo` date the movement of the pitinan in such changed relation. Ggis a second vibrating arm, also mounted on the '13,s'is.

rei-tical shaft or stun r', underneath the tubular arm F and armed at its outer end with a toothed sector, G', the

teeth of' which engage with the teeth of segment or pinion F, and through which the rake-arm is made to roel: or roll in its tubular carrier, to raiseand depress the rake as required. The two vibra-ting arms,-F G,`are incutxiefl upon and vibrate about a comnioncentre, y, and mayy be furthe.` united at or near their swinging ends by means ot matching lips or hoolrsf,` in such manner as eliectually to prevent slipping ot the teeth of' the toothed sector and sector-pinion mounted thereon. '.lhese hooks may be dispensed with, however, if desired. Ou the face of arm F, arranged in about the same vertical plane therewith, isan inclined arm, H, or stop, which serves to limit .the upward throw or degree 'of elevation of the rake. Said stop is made in the form of a flat spring-plate, and may be attached to arm F, 'is shown, or at any other convenient point, and in any suitable manner. i h' are adjustable stops, secured to gear-plate il, the stop h being'made in this instance in'the form of a bolt passing through the gear-plate, and provided with an eccentric head, so that, by the turning ot' the bolt, the position of the head is varied to regulate the extent of vibration of the rake in its discharge-stroke or movement, as desired. z' is a latch, hinged or pivoted at its upper and forward end to the tubnhir arm I", and provided atits opposite end with an angular or Banged hook, which engages with or drops over the rear edge ofthe sector-plate when the rake is raised for itsl return movement over the platform, and serves to prevent'any relative movement of the rake and sector-arms, and to hold the rake in its elevated position. l.: is an angular lever, pivoted in a lug or standard, 7c', and providedat one end with a. friction-roller, l, which is operated upon by a cam-wheel, in such manner as to vibrate the lever c, to :release4 the latch and allow the rake to descend upon the front ot the platform at each revolution of said crank-wheel, through which the vibratory movements of the rake are imparted, as described. I l

The operation ofthe several parts will be readily understood fromy the foregoing description. The rotation of the crank imparts a vibrating movement to the rake-carrier and sector-arms, which are united to a ommen shaft or centre, and geared by the rack and pinion, as explained, and,` being supposed to be moving to the rear to discharge the grain from the platform, the vibration is continued until the scctor-armreachcs tlies'top L, when its further'movement being arrested before the extent of throw of the crank c is reached or provided for, the tubular rake-carrier is caused to travel over the sector-plate, thereby causing the segmenbpinion to traverse the rack, and to roll the rake-arm in its bearings in the carrier-armuntil the rake is thrown up into position shown in iig. 2, when its further movement is arrested by the stop. H, at or near the same instant that the crank reaches the extent of its throw. This change of position of the rake-carrier and sector-arms brings the latch into position to engage with the sector-arm, and thereby prevent the further relative change of said arms until the return vibration of the sector-arm is arrested by stop h', at which instant the lever c acts to release the latch t', when the continued movement ofthe ralie-arm causes the rake to roll forward under the reel, and down upon the front of the platform, into position to repeat its eii'eetive or discharge-stroke.

It will be seen that, by lthis arrangement of the gears and vibrating rake-carrier, sector-arm, and pinion, all the movements of theV rake are made positive, and the usual abrupt descent or fall of the rake is obviated, and the lrake is made to operate equally well in any position the platform may assume in conforming to the surface .of theground. y

What I claim, and desire to secure by Letters Patent, is l 1. '.Lhe gear-plate or casting, made in 'one piece, with bearings for the crank-wheel and vibrating rake-shaft or support, and provided with standards a, and adjustable stops, substantially as described.

2. The arrangement of the crank-wheel which drives the rake relative to the shaft or support ot"the rake,

substantially as described.

3. The arrangement of the crank-wheel in the described relation to theuprights or arms in which its drivingshaft is mounted, as described.

4. 'lhe horizontal shaft, through which motion is imparted to the vibratingrake and rake-gearing, 'mounted in uprights on the gear-plate or its equivalent, and over the crank-wheel, substantially as described.

5. The vibrating rake-carrier and sector-arms, combined and operating substantially as described.

6. The vibrating rake-arm, in combination with its tubular carrying-arm, substantially as described.

7. The vibrating sector-arm, in combination with a. toothed segment or its equivalent on the rake-arm, operating substantially as described. f

8. A latch connected to the vibrating rake-arm, and opera-ting in connection with the vibrating sector-arm to hold the rake in its elevated position, substantially as described.

9. The arrangement of the lever la relative to the vibrating arms, and rake-latch for releasing the same, as set forth.

10. The latch-lever, operated to release the latch by means of a cam or projection on the cranlewheol, as set, forth.

i 11. The employment of a yielding or springstop for limiting the upward throw of the rake. v

12. The arrangement of the spring-stop or its cquivatent upon the vibrating rake-arm, substant'nilly as described.

13. The adjustable dove-tail lug, through which the pitman is connected with the vibrating rake-carricr, substantially as described.

In testimony whereof, witness my hand, this 21st day of December, 1867.
